S-165 dam
S-165
S-165, located in Miami-Dade, Florida, is a state-regulated dam built in 1966 with a primary purpose of flood risk reduction along the Princeton Canal (C-102). Standing at a height of 22 feet, this dam has a storage capacity of 507 acre-feet and a surface area of 23 acres. Despite being rated as low hazard potential, the condition of the dam has not been assessed.
The dam, managed by the state of Florida, plays a crucial role in mitigating flood risks in the region, with a maximum discharge capacity of 450 cubic feet per second. While the dam has not been modified in recent years and its inspection frequency is not specified, it is reassuring to note that it is equipped with state permitting, inspection, and enforcement mechanisms. The dam is also located in an area represented by Debbie Mucarsel-Powell, further emphasizing its importance in the local community.
As water resource and climate enthusiasts, the data on S-165 serves as a reminder of the critical infrastructure in place to manage flood risks in vulnerable areas like Miami-Dade. The dam's role in flood risk reduction and the presence of state regulatory oversight highlight the ongoing efforts to safeguard communities against potential water-related disasters. It is essential to continue monitoring and assessing the condition of such structures to ensure their effectiveness in the face of changing climate patterns and increasing water management challenges.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About S-165
Where does the data for S-165 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
